Question

What is a problem with usability metrics at early stages of design?

a.

They rely on measurements of very specific user actions.

b.

They do not provide a predictive design process for usability.

c.

They assume the availability of specific features like undo buttons.

d.

They focus on specific user actions and situations that may not be known yet.

Answer: (d).They focus on specific user actions and situations that may not be known yet. Explanation:A problem with usability metrics at early stages of design is that they focus on specific user actions and situations that may not be known yet by the designers.
